❑ The image file and bootloader were offered as two separate files
in several earlier software versions. In this version, the two files are
combined into one file.
❑ It is not recommended that you download the bootloader by
itself. If the bootloader on a switch needs to be updated, you
should download the entire AT-S39 software image.
❑ If you are downloading a new AT-S39 software image, the switch’s
current settings (for instance, IP address, port security, and virtual
LANs) are not changed.
❑ If you are downloading a configuration file, the current
configuration of the switch is overwritten by the configuration
contained in the file.
❑ A configuration file contains all switch settings, including the IP
address, subnet mask, gateway address, enhanced stacking
status, and BOOTP/DHCP status.
❑ A configuration file should only be downloaded onto a switch of
the same model from which the configuration file originated (for
example, AT-8024M to AT-8024M). It is not recommended that
you download a configuration file onto a switch of a different
model (for example, AT-8012M to AT-8024GB). The results can be
unpredictable.
❑ A switch running AT-S39 Version 1.4 or earlier must first be
ungraded to Version 1.4.1 or 1.4.2 before you can install a new
AT-S39 image.
❑ A configuration file cannot be edited with a text editor or word
processor.
Caution
Downloading a new AT-S39 image file or configuration file will
cause a switch reset. Some network traffic may be lost.
Here are guidelines that apply to an Xmodem download:
❑ Xmodem can only download a file onto the switch where you
started the local management session. Xmodem cannot
download files through enhanced stacking.
❑ The file to be downloaded must be stored on the computer or
terminal connected to the RS232 Terminal Port on the switch.
